Yellow runny nose and cough are most commonly seen in acute upper respiratory tract infections such as the common cold, but also in upper airway cough syndrome due to allergic rhinitis, so medication needs to be given on a case-by-case basis. If it is caused by the common cold, you need to take a combination of cold and flu medications, such as meprobamate oral solution or cotrimoxazole capsules. If the upper airway cough syndrome is caused by allergic rhinitis, you need to take anti-allergy medication, such as budesonide nasal spray to control the treatment, or oral cetirizine hydrochloride or loratadine to relieve the symptoms of runny nose and cough. If the cough is more intense, cough suppressants such as dextromethorphan, Folcodine solution or codeine may also be appropriate.
